  1. 1. Laser treatment in glaucoma : efficacy and safety

    Författare :Erika Rasmuson; Gauti Jóhannesson; Christina Linden; Björn Lundberg; Mika Harju; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glaucoma; laser treatment; intraocular pressure; glaucoma treatment; glaukom; laserbehandling; ögontryck; glaukombehandling; oftalmiatrik; ophthalmology; oftalmiatrik; ophthalmology;

    Sammanfattning : Glaucoma is a progressive optic neuropathy and the major cause of irreversible blindness worldwide. Although the pathogenesis of glaucoma is not completely understood, the most important risk factor for development and progression of the disease is an elevated intraocular pressure (IOP). LÄS MER

  3. 2. Development and Application of Laser-Induced Emission Techniques for Combustion Diagnostics -High-Resolution Visualization of Turbulent Reacting Flows

  5. 4. Infrared Neural Modulation: Photothermal Effects on Cortex Neurons Using Infrared Laser Heating

    Författare :Qingling Xia; Tobias Nyberg; Björn Granseth; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural modulation; infrared laser; in - vitro experiment; multi - electrode arrays MEA ; heating model; temperature; neural networks; infrared neural inhibition INI ; hyperexcitation;

    Sammanfattning : It would be of great value to have a precise and non-damaging neuromodulation technique in the field of basic neuroscience research and for clinical treatment of neurological diseases. Infrared neural modulation (INM) is a new modulation modality developed in the last decade, which uses pulsed or continues infrared (IR) light with a wavelength of 1200 to 2200 nm to directly alter neural signals.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directed Energy Deposition; Laser Beam; in-situ monitoring; multisensor; resistive pre-heating; Directed Energy Deposition; laserstråle; in-situ övervakning; multisensor; resistiv förvärmning; Production Technology; Produktionsteknik;

    Sammanfattning : Under senare år har omfattande insatser gjorts för att främja mer hållbara flygtransporter i Europa. De konventionella tillverkningsmetoderna som används inom flyg- och rymdindustrin kräver betydande mängder råmaterial, vars utvinning, bearbetning och användning har negativa miljöeffekter. LÄS MER
